Problems solved by technology

First, both solutions are equivalent to configuring only one available SPS configuration for the UE, so that even if the UE is not scheduled this time, the PUCCH resource position is still reserved, causing unnecessary waste; second, Solution 1 does not use the flexible scheduling function of the PDCCH field. Although Solution 2 uses the flexible scheduling function of the PDCCH field, the actual effect is the same as that of Solution 1, and no obvious benefits are introduced.

Abstract

The present invention relates to a PUCCH channel dynamic allocation method for SPS services, comprising configuring the same PUCCH channel resource group for multiple SPS service terminals, and sending resource index values ​​of each PUCCH channel resource in the configured resource group to each SPS service Terminal; For the SPS service terminal that has downlink SPS service arrival, determine the PUCCH subframe corresponding to the time that the SPS service terminal should be scheduled according to the timing relationship; search for the PUCCH channel resource group configured for the SPS service terminal in the determined Unoccupied resource blocks in the PUCCH subframe, and send the location identifier of the PUCCH channel resource to which the found resource block belongs to the SPS service terminal. The resource blocks of the same PUCCH channel in different subframes can be allocated to different SPS service terminals for use, without a fixed allocation of a PUCCH channel for each SPS service terminal, which improves the resource utilization rate of the PUCCH channel.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a PUCCH channel dynamic allocation method and device for SPS services. Background technique [0002] In an LTE (Long Term Evolution, long-term evolution system) system, a PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) mainly carries uplink control information (Uplink Control Information, UCI) fed back to a base station. Uplink control information includes: SR (Schedule Request, scheduling request), ACK / NACK (Acknowledgment, positive acknowledgment / Negative Acknowledgment, negative acknowledgment) and CQI / PMI (Channel Quality Indicator, downlink channel quality indicator / Precoding Matrix Indicator, precoding matrix Indication) and RI (Rank Indicator, level indication), corresponding to the Format1, Format1A / 1B and Format2 / 2A / 2B formats of the PUCCH. details as follows: [0003] Format1: used for UE (User Equipment, user equipment)...
